IMPROVEMENT IN REFRIGERATOR.

To all 'whom it 'may concern:

cle serving alsoas ya reservoir for a supply of cold water to be used for drinking-purposes.

Another important feature of my invention is the vshape of the provision-chamber, it`haviug an arched or peaked top, so that particles of condensed moisture, instead of dropping upon the provisions, (which would be the case if the chamber had a flat roof,) will be directed from the slopingtop to the vertical sides of the chamber, and will thence escape through a small utubev in the bottom of the said chamber, all as fully described hereafter.

In order to enable others to make and apply my invention, I will now proceed to describe the mode of constructing and using the same, reference being hadl to the accompanying drawing, which forms a part of this specilication, and in which- Figure 1 is a vertical sectional view of lnyimproved refrigerator Figure 2, a vertical section 142, iig. 1; and 'Figure 3, a sectional plan view, on the line v3?-4,

of the same, on the line parts throughout the several views. y,

The outer `casing'Ais similar in shape-to that of ordinary refrigerators, consisting of a square Wooden box, lined with any suitable non-conducting packing.

lVithin this boris arranged a-thin metal casing, B, the sides of which are of the peculiar curved form illustrated in iig. 1, while its ends are vertical, as shown in fig. 2, and in contact with the ends -of the box, or with the packing with which the box is lined. p -A second thin'metal casing, (l, having an arched or pointed top, a, is'so suspended within the casing B, and is so curved, that the space between the sides ofthe two casings, from the top to about the line 'z-z, iig. 1,4 shall gradually decrease in width, while-from this line downward, and between the bottoms of the two casings, the space shall be quite narrow, but of regular width.

The Ainterior of the casing C forms the provisionchamber, and is marked F in the drawing, while the space between the two casings constitutes the icereceptacle, and is marked H.

A cock, g, communicates with the lowest point of the latter, as shown in iig. l.

Access is obtained to the interior of the provisionchamber through a door, b, at one end of the box A, and to the interior of thei-ice-receptacle through an opening or passage, c, in the top of the casing B,

' which is closed by a suitable cover, f.

In order to prevent the warm external air frontentering the ice-receptacle when water is drawn off from the same through the cock y, the cover f is provided with a tlange or lip, t, which .projects intoa groove `formed in the top of the box A, and which' is lled or partly filled with water.

The only air which is permitted to enter the icel receptacle passes first into the provision-chamber F, through a small`tube, j, and is thoroughly cooled in the said chamber before it escapes from the same, through a secondtube, j. (See iig. 2.)

In lling the receptacle H with lice, care must be taken to introduce small pieces l'irst, so that the entire space between the casings B and C, down to about the line z-z, may be filled.A

These pieces will become wedged in between the two casings, and w'ill be maintained in close contact with the walls of the provision-chambem gradually 1 moving downward as they are melted away, and being replaced by other pieces from above.

A small quantity of Water previously introduced "into the ice-receptacle, but maintained at so low a point in the same as not to bebroug'ht in contact with the ice, will be kept constantly cool by the drippings from the latter, and while aiding in reducing the temperature within the provision-chamber,may also be used for drinking-purposes, being drawn off', as it is required, vthrough the cock g.

The above arrangement enables the entire upper portion and sides of theprovision-chamber to be surrounded by ice, which is so suspended or 'wedged between the two casings, that it cannot fall into the water, and therefore 'melts very gradually, the refrigerator,l consequently, after having been once lled, requiring but a small quantity of ice, and replenishing at comparatively long intervals. f

Another advantage arising from the arched form ot' the top of the provision-chamber is that the contents of the latter are kept dry, the condensed moisture, instead of 'dropping upon the provisions, as it would from a flat roof, running from the point a down the sides of the chamber, and escaping through the tube j.

The cornerA spaces :c x, instead of being filled with non-conducting packing, as shownY in iig. 1*, might be converted into chambers for the reception of small articles requiring to be kept cool.

I 'claim as my invention, and desire to secure hy Lett-ers Patent 1; The provision-chamber F, having au arched or peaked roof, a, in combination with the surrounding Casing B, -form'rn? an ice-reservoir above, and n. waterreservoir round the chamber F, substantially as set forth.

2. The arrangement described, in respect; to the provision-chamber F, and ice-receptacle H, of the tubes j and j.

In testimony whereof, I have signed my name to this specification, in the presence of' two subscribing witnesses.
